We have written a few days ago about CobaltController, an application which allows Windows Mobile users to use PS3 Bluetooth game controllers to control games on their smartphones.
Cobaltikus has now gone one step further and enabled support for the Bluetooth-powered Wii Remote also, a controller which many more people have in a cupboard somewhere.
The software currently only supports devices with the Widcomm Bluetooth stack, which includes most recent HTC devices. It does not yet support the accelerometer in the Wiimote, but this is just a question of time.
